摘要
En 中文
We summarize the development of microfabricated atomic frequency references at NIST. The physics packages of these devices have volumes near 10 mm(3) and power dissipation below 150 mW, and can potentially achieve a fractional frequency instability in the range of 10(-11) over long periods. A fully integrated frequency reference could find application in portable, battery-operated devices such as global positioning system (GPS) receivers and cellular telephones.
